The mean number of acres for each park for the two cities is:

City A: 7.5

City B: 7.3

The range for the number of acres for parks for the two cities is : 8

Explanation:

The table shows the number of acres for each park in the two cities.

City A: 6 9 10 7 10 10 2 5 8 8

City B : 5 10 8 11 7 12 6 5 4 5

City A:

Minimum acre of park=2

Maximum acre of park=10

Range=Maximum-Minimum

Range=10-2

Range=8

Now mean is calculated as:

`Mean=(6+9+10+7+10+10+2+5+8+8)/(10)\\\\\\Mean=(75)/(10)\\\\Mean=7.5`

City B:

Minimum acre of park=4

Maximum acre of park=12

Range=Maximum-Minimum

Range=12-4

Range=8

Now mean is calculated as:

`Mean=(5+10+8+11+7+12+6+5+4+5)/(10)\\\\\\Mean=(73)/(10)\\\\Mean=7.3`
